Tomstat, if those LEDs are spaced the same on your M-1.0t as on the M-400t, then they represent 0db, -5db, -10db, -20db, -40db and - infinity. Assuming 0db=200WPC, then the first one from the top would represent about 60WPC, the second one from the top represents 20WPC, the third one from the top represents 2WPC, the next one down 0.02WPC (1 fiftieth of a watt) and the last one represents next to no power being generated. you could approximately double those figures for the M1.5t.

I've never managed to get the top LED to even flicker on my M-400t and only had the -5db LED light up once or twice and that volume was close to deafening for me, so if you are using 200WPC on average on your M-1.5t, either your listening room is huge, your speakers are really inefficient, you like it really loud or you have gone deaf .... Or maybe I'm the weenie who doesn't like to listen as loud as you guys do .....

My ribbons are 2 ohms, and I get the meters bouncing around 75% at times...

The other amp, ODL HT-2 is rated @ 260 watts RMS per channel into 4 ohms, which is what the 12" subs in the speakers are rated....

So looks like I have to potential of running around 1400-1500 watts per channel, and the only thing that's going to blow would be the ribbons

Show me anyone else dumping 1000w straight into their ribbons.
I really plan on re-kaptoning my ribbons soon... but before I do, I plan on TRYING to fry them. Maybe I'll hold off till CarverFest, and do a live demo. I want to see the magic smoke crackle out of a ribbon. I would hope screaming 1200 watts into a ribbon would kill it.
So far, these ribbons have turned a TFM-45 into their 1st victim, let's see if they can withstand the wrath of the Lightstar.....
